6 Claims.

This invention relates to valve-tools, and more particularly to valve-tools for removing the valves or valve-assemblies of Ford V8 engines.

For various reasons, it is a difficult and timeconsuming operation to remove the poppetvalves from certain engines, such, for example, as the Ford V8 engine.

One object of this invention, therefore, is to provide an improved valve-tool for more quickly and easily removing valves or valve-assemblies from engines.

Another object of this invention is to provide an improved va1ve-tool formed of simple elements readily manufactured and readily assembled to produce a durable and eiiicient tool at minimum cost.

With the above and other objects in view, as will appear to those skilled in the art from the present disclosure, this invention includes all features in the said disclosure which are novel over the prior art.

In the description and claims, the various parts and steps are identified Iby specific names for convenience, but they are intended to be as generic in their application as the prior art will permit.

Referring to the drawings, the particular fragmental portion of an engine or cylinder-block 20 illustrated in Figs. 1 and 2, represents part The poppet-valve assembly, generally designated by the numeral 2l, is shown mounted in the engine-block 20, and includes the valve-element 22 which has a valvehead 23 on the upperend thereof, a valve-stem 24, a limit-flange 25, and an enlarged lower end 26. A split guide or bushing 21 including two bushing-halves 28, serves as a guide to slidably support the valve-stem 24 for its operation. A valve-spring 29 engages between the bushing 21 and a valve-keeper or spring-retaining clip 30 which clip rests against the end 26, the spring 29 forcing the valve-element 22 into its closed position. The foregoing described valve-assembly is held in its position in the 'cylinder-block 20 by means of a bushing-retainer or retainingclip 3| which normally seats in a counterbored recess or seat 32 and prevents the bushing 21 from being forced outwardly by the spring 29.

In operation, the end 26 of the valve-element 22 is actuated Iby the slidably-mounted :tappet or cam-plunger 33 which in turn is actuated by the cam 34 on the cam-shaft 35. The valve-head 23 is adapted to properly t the valve-seat 36 of a valve-port 31 of the cylinder-block 20. The valve-assembly illustrated in Figs. 1 and 2 represents one valve of which there are many in the engine. The foregoing described engine and valve-construction is of usual form.

The particular embodiment of my valve-removing tool for removing the valve-assembly just previously described is generally designated b-y the numeral 38 and includes a body-member 39 having a forcer-head 40 to which a tubular lever 4l is pivoted by a pin 42 bearing in ears 430i lever 4 I, and in which lever 4 I is slidably mounted a member 44 which serves as a hammer-bar and as a lever-extension. The body-member 39 shown in perspective in Fig. 17, is preferably made as a unitary forging, although it could be made in any fother desired suitablel way. A ful- Vcruni l5 is pivoted by a pin 46 to a pair of Vears the lockinglugs 5,4,

4'! formed integral with the lever 5l.' Y

The body-member 39 has a side-opening recess, generally designated by the numeral 48, which includes a valve-head-receiving recess-portion t9,V

prying-tool-receiving recess-portions 59, and a valve-stem-receiving recess-portion 5l and a valve-stemV-receiving recess-portion 52. The recess-portion 5I is large enough to clear the annular shoulder or limit-flange 2 5 of the valvestem, while the recess-portion 52 is of a size to freely fit the cylindrical portion 53 oi theV valve-stem. The valve-element 22 is capable of entering the recessliS `by a transverse movement relatively between the valve-element 22 and the body-member 39 when the head 23 of the valveele'ment is in the raised position indicated by broken lines in Fig. 1, so as to have thejhead 23 of the valve-element above the pair of locking-projections or lugs 5s.

The lower end or pnsher-end82 of the body-member 39 has a diameter small enough to just easily permit the end 82 to extend freely into the upper portion of the passage 86 in the engine block 20 and thus bring the recess 52 properly centered relatively tothe valve-stem 24. The'pusher-end 32 has a pair of sharp spaced--apartv inner edgeportions t? adapted to engage against the mafchined flat upper central surface portion of the bushing 2l, and a pair of sharp outer edge-'portions 88 extending from the Y portions 8l tothe opposite sides of the pusher-end 82 and which portions B8 normally clear the bushingy 2l but engage the upper surface of the bushing 2T ifwfor any reason the portions 8'! slip from their proper position during removal of the valve-assernbly. If such slippage occurs, the surface 52,,swings vhack away from the cylindrical portion 5,3 of the valve-stem 2d, with the consequencev that the outer sharp edge portions 88 swing downward ,due to their location nearer the plane. of front face 89 of the body-member 39 than the innerY sharp edge-portions 8l.

In order to prevent ping off the edge of the engine-blockl 29 an, angle? plate 99 (Figs. 1, 2 and 19) may be employed..

As the tool 3B is pushed further into the valve-port 31, it is rocked or swung toward the position illustrated in full lines in Fig. 1, and during tlns transverse rocking and endwise movement of the tool 38 into the valve-port 31, the clearance-chamfers S3 permit the lower-end or pusher-portion 82 of the body-member 39 to pass along between the flange 25 and the wall of the valve-port 31 to bring the tool toward the position shown in Fig. 1. When the tool 38 is near this position of insertion, there is then sufficient freedom of the lower-end portion 82 of the body-member 35 in the port 31 to permit the flange 25 to pass outside and above the locking-lugs 54, whereupon the tool 38 can be swung transversely to bring it into the exact position shown in Fig. l, to thus cause the valve-element 22 to move into the recess 43, as shown by the dotted-line position of valve-head 23 in Fig. 1. During this transverse and endwise movement of the tool 38 to the position shown in Fig. 1, the claw-ends 8| of the prying-tool 19 are received in the recess-portions i). By removing the prying-tool 19, the valve-spring 29 is permitted to pull the valve-head 23 down to the full-line position of the valve-head 23 shown in Figs. l and 5, to thus seat the head 23 on the lifter-seat 55. When the tool 33 has been thus moved to the position shown in Fig. 1, the valveelement 22 will then be in the recess 48 in the position shown in Figs; 1 and 5, with the limitflange 25 located behind the two locking-lugs 54 which thus prevent any transverse or outward movement of the valve-element 22.

The hammer-element 44 is now drawn out or extended and then moved quickly in to cause its lower end 62 to strike a blow against the forcerhead 49 of the body-member 39, to cause the pusher-end 82 at the lower end of the bodymember 39 to strike a blow against the split bushing 21 and force the valve-assembly 2l downwardly through the passage 86 in which it is frictionally seated, to thus move the bushing 21 to a position illustrated in Fig. 2, whereupon the bushingretainer 3l (Fig. l) can be readily removed from its position in the groove 34 of the bushing 21.

The lever i is now swung to a position such as illustrated in Fig. 2, to bring the fulcrum 45 into engagement with a surface of the cylinderblock 25B, or against the angle-plate 90 and its flange Q3 where the angle-plate d@ is employed, whereupon pressure is exerted on the lever or the hammer-bar or lever-extension Sli to thus partly force or raise the valve-assembly axially out of the port 31 in which it is located. In order to at all times maintain the valve-element 22 in substantial alignment with its proper position in the bushing 21 and avoid distorting or bending the valve-element 22, the valve-assembly is only moved a relatively-short distance at one movement of the lever M, the fulcrum 425 being adjusted to successively longer and longer lengths, between which adjustment another pry is taken on the lever 4! or its extension 44, to thus further pull the valveassembly out of its location in the cylinder-block. After removing the valveassembly from the cylinder-block, each of the other valve-assemblies is removed from the cylinder-block in a similar manner.

The invention may be carried out in other specific ways than that herein set forth without departing fromy the spirit and essential characteristics of the invention, and the present embodiment is, therefore, to be considered in all respects as illustrative and not restictive, and all changes coming within the meaning and equivalency range of the appended claims are intended to be embraced therein.
